Rescue workers head to the site of a massive landslide on Wuxiangang Hill of Sanxi village in Dujiangyan city in southwestern China's Sichuan province, July 10, 2013.

Flooding in western China, the worst in 50 years for some areas, triggered a landslide Wednesday that buried about 30 people, trapped hundreds in a highway tunnel and destroyed a high-profile memorial to a devastating 2008 earthquake.
